Question

Is the use of concrete in the home bad for your health?

Asked by Julie Lefebvre

Dear Pros, We are in the middle of designing our new home which we would like to be a as energy efficient, non-toxic and green as possible, within a limited budget. We are thinking of using a lot of concrete (with recycled content) for floors and certain walls as thermal mass for passive heating. However, I am concerned that concrete releases VOCs even after it is dry. Is this true? Are there any types of concrete mixes that are better than others? Or is there a healthier alternative to concrete altogether for this purpose? Thank you for your help, Julie
